The PPC version of Flasher-3.5 works fine on my black MacBook. It was a simple answer, and yet I could not find it anywhere.

Also, make sure that if you are flashing eMMC too, you omit the -R when you are *first* flashing the FIASCO .bin file.

770Flasher *will not work* if you are trying to flash the eMMC because it automatically reboots your N900 after flashing the FIASCO .bin, so you can't get to that necessary second step for eMMC. Perhaps that could be addressed in a new version.
